WILLIAM W. GIBB, OF II/IPERIAL, NEBRASKA.

GRAINLDBILL ATTACHMENT.

Application filed. February 10, 1922.

To all whom it may concern:

Be it known that WILLIAM Gina, a citizen of the United States ofAmerica, residing at Imperial, in the county of Chase and State ofNebraska has invented new and useful Improvements in Grain-DrillAttachment-s, of which the following is a specification.

The object of the invention is to provide a grain drill assembling andriding frame for use in the control of wheat planting machines when usedin the corn field for drilling wheat between and parallel with the rowsof corn, and the planting of which is conducted after the corn hasreached a considerable height; and more particularly it.

the object. to provide an apparatus for this purpose which will enable asingle operator while occupying a riding frame to control a plurality ofplanters or planting mechanisms operating respectively in the spacesbetween different rows or hills of corn the adjustment of the assemblingand riding frame to the spacing between the rows of corn beingaccomplished automatically and without effecting the position of theseat of the rider or operator; and with these objects in view theinvention consists in a construction and combination of parts of whichapreferred embodiment is shown in the accompanying drawings, whereinFigure l is a plan view of an apparatus embodying the invention showingthe same in connection with two rain drills or planting mechanisms eachof which is adapted to be drawn by a single draft animal.

Figure 2 is a side view of the same.

Figure 3 is a rear view of the apparatus.

Figure i is a detail view showing the con nection between the frame ofthe grain drill and the upright of theriding frame.

Figure 5 is an enlarged sectional view of the cross bar of the graindrill frame.

The riding frame which is indicated generally at is illustrated in thedrawing as used in connection with two grain drills indicated at 11which are shown and may be of the conventional or any preferred typehaving independent draft appliances 12 to which may be connected horsesor other draft animals designed respectively to travel in the intervalsbetween rows of grain, and without attempting to specifically describethe particular grain drills herein showii. it may be stated that eachembodies essentially a frame L3 having a plurality of cross bars SerialNo. 535,560.

14 and carried by the front wheel 15 and rear castor wheels 16, and seedboxes 1? from which extends a spout 18, and a drilling disk 19, all asclearly shown in Figure such mechanism as in the ordinary practice beingguided by suitable handles 20.

The riding attachment which is designed as a means of assembling andholding in proper relation a plurality of grain drills for simultaneousoperation between different rows of corn consists essentially of an archhaving uprights 2i and a transverse member or cross bar constructed inthe form of a toggle. lever with a centrally pivoted intermediate membcr23 terminally connected by the links 2 respectively with. the uprights2i, and Said uprights being supported b wheels mounted upon brackets 26which are swiveled by means of the sleeves 27 upon the uprights. Toassist in maintaining the links 21!; in a horizontal plane, the latterare provided, with horizontal members Q-l also having terminalconnections with the uprights 21. These sleeves are supported and heldin adjusted relation with the uprights by means of collars 28 held inplace by setscrcws 29 or the equivalent thereof.

The connection between each drill frame and the riding frame is effectedin the construction illustrated by extending one of the cross bars 14:of the former through a yoke 30 formed by slotting the lower end of theupright 21 and extending a transverse bolt 31 through the bar inspanning relation with the yoke. The opening 32 in the cross bar ispreferably cut away or enlarged; terminally as indicated clearly inFigure 5 to permit of a rocking movement in a vertical plane of thedrill frame while maintaining the assembly of said frame with theupright of the arch.

The said uprights are provided at their upper ends with crank arms 33preferably extended in substantial parallelism with the path of movementof the drill frames and preferably rearwardly from the transversevertical plane of the uprights and are terminally connected by atransverse bar 34 with which they have pivotal connection by means ofthe sleeves and carried by this transverse bar is a riding seat 36 whichby reason of the rearward direction of said crank arms 3?) is disposedsubstantially in the transverse plane of the axes of the supportingwheels .25 which uphold the riding frame and which by reason of themounting thereof are free til) erably foot rests 38 are attached to thefront end of said brace for the convenience of the occupant of the seat.

The transverse seat supporting bar 34: be-

ing of unitary construction and therefore of invariable length andhaving bearing heads 35 in which the terminals of the crank arms aremounted, it will be obvious that any tendency of the drill frames tomove toward or from each other will cause a corresponding movement oftheuprights 21 moving about the axes represented by the pivotalmountings of said crank arms upon the seat supporting bar, but anytendency of either upright to move transversely will by reason of thetoggle lever cause a cone spending movement of the opposite upright, sothat in all relative positions as to spacement of the grain drills theseat :36 will re- I main in the central position between the planes ofsaid drills. As there is no restriction to the lateral movement of thegrain drills it is, therefore, obvious'that in order to maintain aproper working relation of the parts it is only necessary for theoccupant of the seat to keep the draft animals in the proper positionsin the intervals between the rows of corn, and the direct following ofthe draft animals by the grain drills will be accommodated by theyielding one way or the other of the toggle lever connection between theuprights of the arch, to insure a proper operation the mechanism.

The vertical extent of the uprights as will be obvious is designed toprovide for locating the cross bar of the arch above the plane of thecorn in the row between those in which the drills are operating or at asufiieient distance from the ground to come in contact with therelatively flexible portions of the corn stalks, so that the deflectionor bending of the latter by the contact of the cross bar will involve nobreakage or other injury thereto.

Having described the invention, what is claimed as new and useful is:

A drill coupling structure comprising uprights mounted upon the'drills,supporting wheels caste-red to the uprights, crank arms pivoted at theupper ends of the uprights, a transverse bar pivotally connected withthe crank arn'is, a seat standard monntedat the intermediate portion ofthe transverse bar, a link pivoted to the seat standard and outer linkspivoted at their inner ends to the ends of the first mentioned link andpivoted at their outer ends to the uprights and crank arms.

In testimony whereof he alh'xes his signature.
